STOVE-BACK.

SPECIFICATION forming part of Letters Patent No. 369,356, datedSeptember 6, 1887.

Application filed October 15, 1886. Serial No. 216,367. (AIodeL) To allwhom it may concern.-

Be it known that I, W ILLIAM C. METZNER, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Steve Backs; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appcrtains to make and use the same, reference beinghadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to adjustable stove backs or linings which areadapted to be extended or contracted both horizontally and vertically tofit fire-boxes of various sizes.

In the accompanying drawings, Figures 1, 2, and 3 are rear elevations ofportions of the back. Fig. i is a rear elevation of the eon1- pleteback. Fig. 5 is a front elevation of the complete back. Fig. 6 is a viewof the end of the back at the left in Fig. 4. Fig. 7 isa section in lineac a: of Fig. 5.

A, shown reversed and by itself in Fig. 1,is the main plate, and formsthe greater part of the front of the back. This comprises the threeparts A, A", and A. The upper edge of the part A is curved rearwardly toconform to the fire-box. The portion A is set forward far enough fromthe part A to make an offset, a, deep and wide enough to receive theplate B. At one end of the part A the portion A is set backward to makean offset, a, to receive the edge of the end lining of the firebox.Thispart A, as shown,does not extend to the bottom of the plate A, butstops at the line of junction between A and A. It may,however, extend tothe lower edge of A'-.

B is a plate of the same length as the plate The part 13 of said plateB, which lies below the part A, is set backward to correspond with Atthis end of the plate B is an upward extension, B, which overlies therear of the part A, such extension being set back from the part B. Saidextension is provided with a vertical slot, 13 and a bolt, A pass ingthrough said slot and a hole, A, in the part A, binds said platestogether. A web, B, which is shown as triangular in shape,and

set forward of the part B in the same plane with B, may extend from theside of the extension B downwardly to the upper edge of the plate B tostrengthen said extension. The two plates A and 13 together form an evensurface to which the remaining plates may be applied.

C is a plate covering the upper portion of the even surface formed bythe plates A and B, and extending a short distance beyond said plates atthe end opposite the part A and the extension B. Vhen thestrengtheningweb 'B" is used, the corner of the plate is cut olf,

so that it may fit smoothly with the web. This plate lies in the sameplane with the parts A and B Near its middle it is provided with one ormore horizontal slots,G, anda bolt, A, passing through a hole, A, inplate A and one of said slots 0, binds the plate 0 to the plate A.

D is a plate composed of the parts D and D The part D is of proper sizeto lie in the space over the plate 13 below plate 0, while the part D isset rearwardly and extends upwardly over the lower portion of the plate0. The part D of the plate D is provided near its middle with one ormore horizontal slots, D and a bolt, B, passing through a holc,B, in theplate B and one of the slots D binds said plate D to the plate 13. Theouter end of the part D of the plate D is provided with a vertical slot,D", and a bolt, 0", passing through a hole, 0 in the plate G, binds saidplates C- and D together.

The plates thus united form a stove-back with practically straight andcontinuous edges. By loosening the bolts A and O the plates B and D maybe lowered to increase the height of the back, and by loosening thebolts A and B the plates 0 and D may be shifted laterally toincrease'the length of the back.

The plates A and B may be provided with additional holes, A and B, toreceive the bolts A and B when the back is to be extended to an extralength.

I am aware that an adjustable stove-back has been heretofore made offour overlying plates, and I do not broadly claim such a back.

I claim as my invention-- In an adjustable stovebaok, the combina tionof the plate A, having the offset a, the plate 13, lying in such offsetand having the extension B, through which a bolt binds said of thelatter and said plate D farthest from plate to the plate A, a plate, 0,covering the theextension B, substantially as shown and upper portion ofthe even surface formed by described. the plates A and B, and bound tothe plate A In testimony whereof I affix my signature in 5 by a boltpassing through the plates A and 0 presence of two witnesses.

at about the middle of the upper portion of the plate A, and a plate, D,overlying the WILLIAM METZNER' plates B and O, and bound to the plate Bby Witnesses: a bolt at about the middle of the latter plate CYRUS KEHR,[o and bound to the plate 0 by a bolt at the end WILLIAM B. NICHOLSON.
